Why is the spectrum of light seperated into its components of colour when white light is directed to a prism?
The different colours in the white light bend away from the normal line at different angles when entering prism
The different colours in the white light bend towards the normal line at different angles when entering prism
The different colours in the white light bend away from the normal at same speed to each other when entering prism
The different colours in the white light bend towards the normal at same speed to each other when entering prism
When light waves are captured in matter and transferred to a new form of energy we call this:
Absorption
Reflection
Refraction
Dispersion
